The massive investigations which are underway following the Brussels attacks have revealed that the Islamic State of Iraq and the Levant (ISIS) are in various stages of planning multiple additional attacks across Europe.
According to the Guardian, US counterterrorism officials have stated that a combination of electronic intercepts, human sources and database tracking indicates several possible targets had been picked out by the ISIS operatives over the last few months since the Paris attacks.
According to a senior Belgian counter-terrorism official, investigators believe the Brussels ISIS cell were composed of two teams who were planning a larger attack or series of attacks in Belgium at a later date.
After the discovery of Salah Abdeslam's hiding place last week, investigators believe the second team sped up their plans and that the team which consisted of the Bakraoui brothers and at least two others now on the run.
Investigators state that the first team was composed of Salah Abdeslam, and Mohammed Belkaid, the suspected commander of the Paris and Brussels attack cell, who was shot dead during the firefight at Abdeslam's hiding place last week.
Police recovered an ISIS flag, a Kalashnikov, detonators, and ammunition at the safehouse, suggesting that Belkaid and Abdeslam were planning attacks in Brussels similar to that in Paris.
